DETAILED DESCRIPTION OF THE INVENTION

In the following it is understood that the term usability refers to ametric scoring value for judging the ease of use of a target web site. Aclient refers to a sponsor who initiates and/or finances the usabilitystudy. The client may be, for example, a marketing manager who seeks totest the usability of a commercial web site for marketing (selling oradvertising) certain products or services. Participants may be aselected group of people who participate in the usability study and maybe screened based on a predetermined set of questions. Remote usabilitytesting or remote usability study refers to testing or study inaccordance with which participants (referred to use their computers,mobile devices or otherwise) access a target web site in order toprovide feedback about the web site's ease of use, connection speed, andthe level of satisfaction the participant experiences in using the website. Unmoderated usability testing refers to communication with testparticipants without a moderator, e.g., a software, hardware, or acombined software/hardware system can automatically gather theparticipants' feedback and records their responses. The system can testa target web site by asking participants to view the web site, performtest tasks, and answer questions associated with the tasks.

FIG. 1A is a simplified block diagram of a user testing platform 100Aaccording to an embodiment of the present invention. Platform 100A isadapted to test a target web site 110. Platform 100A is shown asincluding a usability testing system 150 that is in communications withdata processing units 120, 190 and 195. Data processing units 120, 190and 195 may be a personal computer equipped with a monitor, a handhelddevice such as a tablet PC, an electronic notebook, a wearable devicesuch as a cell phone, or a smart phone.

Data processing unit 120 includes a browser 122 that enables a user(e.g., usability test participant) using the data processing unit 120 toaccess target web site 110. Data processing unit 120 includes, in part,an input device such as a keyboard 125 or a mouse 126, and a participantbrowser 122. In one embodiment, data processing unit 120 may insert avirtual tracking code 124 to target web site 110 in real-time while thetarget web site is being downloaded to the data processing unit 120. Thevirtual tracking code 124 may be a proprietary JavaScript® code, wherebythe run-time data processing unit interprets the code for execution. Thetracking code 124 collects participants' activities on the downloadedweb page such as the number of clicks, key strokes, keywords, scrolls,time on tasks, and the like over a period of time. Data processing unit120 simulates the operations performed by the tracking code 124 and isin communication with usability testing system 150 via a communicationlink 135. Communication link 135 may include a local area network, ametropolitan area network, a wide area network. Such a communicationlink may be established through a physical wire or wirelessly. Forexample, the communication link may be established using an Internetprotocol such as the TCP/IP protocol. Activities of the participantsassociated with target web site 110 are collected and sent to usabilitytesting system 150 via communication link 135. In one embodiment, dataprocessing unit 120 may instruct a participant to perform predefinedtasks on the downloaded web site during a usability test session, inwhich the participant evaluates the web site based on a series ofusability tests. The virtual tracking code (i.e., a proprietaryJavaScript®) 124 may record the participant's responses (such as thenumber of mouse clicks) and the time spent in performing the predefinedtasks. The usability testing may also include gathering performance dataof the target web site such as the ease of use, the connection speed,the satisfaction of the user experience. Because the web page is notmodified on the original web site, but on the downloaded version in theparticipant data processing unit, the usability can be tested on any websites including competitions' web sites.

All data collected by data processing unit 120 may be sent to theusability testing system 150 via communication link 135. In anembodiment, usability testing system 150 is further accessible by aclient via a client browser 170 running on data processing unit 190.Usability testing system 150 is further accessible by user experienceresearcher browser 180 running on data processing unit 195.

Although a data processing unit is illustrated, one of skill in theart will appreciate that data processing unit 120 may include aconfiguration of multiple single-core or multi-core processorsconfigured to process instructions, collect usability test data (e.g.,number of clicks, mouse movements, time spent on each web page,connection speed, and the like), store and transmit the collected datato the usability testing system, and display graphical information to aparticipant via an input/output device (not shown).

FIG. 1C is a simplified block diagram of a user testing platform 100Caccording to yet another embodiment of the present invention. Platform100C is shown as including a target web site 130 being tested by one ormore participants using a standard web browser 122 running on dataprocessing unit 120 having a display. The target web site 130 is shownas including a tracking program code configured to track actions andresponses of participants and send the tracked actions/responses back tothe participant's data processing unit 120 through a communication link115. Communication link 115 may be computer network, a virtual privatenetwork, a local area network, a metropolitan area network, a wide areanetwork, and the like. In one embodiment, the tracking program is aJavaScript® configured to run tasks related to usability testing andsending the test/study results back to participant's data processingunit for display. Such embodiments advantageously enable clients usingclient browser 170 as well as user experience researchers using userexperience research browser 180 to design mockups or prototypes forusability testing of variety of web site layouts. Data processing unit120 may collect data associated with the usability of the target website and send the collected data to the usability testing system 150 viaa communication link 135.

In one exemplary embodiment, the testing of the target web site (page)may provides data such as ease of access through the Internet, itsattractiveness, ease of navigation, the speed with which it enables auser to complete a transaction, and the like. In another exemplaryembodiment, the testing of the target web site provides data such asduration of usage, the number of keystrokes, the user's profile, and thelike. It is understood that testing of a web site in accordance withembodiments of the present invention can provide other data andusability metrics.

Information collected by the participant's data processing unit isuploaded to usability testing system 150 via communication link 135 forstorage and analysis.

FIG. 2 is a simplified block diagram of an exemplary embodiment platform200 according to one embodiment of the present invention. Platform 200is shown as including, in part, a usability testing system 150 being incommunications with a data processing unit 125 via communications links135 and 135′. Data processing unit 125 includes, in part, a participantbrowser 120 that enables a participant to access a target web site 110.Data processing unit 125 may be a personal computer, a handheld device,such as a cell phone, a smart phone or a tablet PC, or an electronicnotebook. Data processing unit 125 may receive instructions and programcodes from usability testing system 150 and display predefined tasks toparticipants 120. The instructions and program codes may include aweb-based application that instructs participant browser 122 to accessthe target web site 110. In one embodiment, a tracking code is insertedto the target web site 110 that is being downloaded to data processingunit 125. The tracking code may be a JavaScript® code that collectsparticipants' activities on the downloaded target web site such as thenumber of clicks, key strokes, movements of the mouse, keywords,scrolls, time on tasks and the like performed over a period of time.

Data processing unit 120 may send the collected data to usabilitytesting system 150 via communication link 135′ which may be a local areanetwork, a metropolitan area network, a wide area network, and the likeand enable usability testing system 150 to establish communication withdata processing unit 120 through a physical wire or wirelessly using apacket data protocol such as the TCP/IP protocol or a proprietarycommunication protocol.

Usability testing system 150 includes a virtual moderator softwaremodule running on a virtual moderator server 230 that conductsinteractive usability testing with a usability test participant via dataprocessing unit 120 and a research module running on a research server210 that may be connected to a user research experience data processingunit 195. User experience researcher 181 may create tasks relevant tothe usability study of a target web site and provide the created tasksto the research server 210 via a communication link 185. One of thetasks may be a set of questions designed to classify participants intodifferent categories or to prescreen participants. Another task may be,for example, a set of questions to rate the usability of a target website based on certain metrics such as ease of navigating the web site,connection speed, layout of the web page, ease of finding the products(e.g., the organization of product indexes). Yet another tasks may be asurvey asking participants to press a “yes” or “no” button or writeshort comments about participants' experiences or familiarity withcertain products and their satisfaction with the products. All thesetasks can be stored in a study content database 220, which can beretrieved by the virtual moderator module running on virtual moderatorserver 230 to forward to participants 121. Research module running onresearch server 210 can also be accessed by a client (e.g., a sponsor ofthe usability test) 171 who, like user experience researchers 181, candesign their own questionnaires since the client has a personal interestto the target web site under study. Client 171 can work together withuser experience researchers 181 to create tasks for usability testing.In an embodiment, client 171 can modify tasks or lists of questionsstored in the study content database 220. In another embodiment, client171 can add or delete tasks or questionnaires in the study contentdatabase 220. In yet another embodiment, client 171 may be userexperience researcher 181.

In one embodiment, one of the tasks may be open or closed card sortingstudies for optimizing the architecture and layout of the target website. Card sorting is a technique that shows how online users organizecontent in their own mind. In an open card sort, participants createtheir own names for the categories. In a closed card sort, participantsare provided with a predetermined set of category names. Client 171and/or user experience researcher 181 can create proprietary online cardsorting tool that executes card sorting exercises over large groups ofparticipants in a rapid and cost-effective manner. In an embodiment, thecard sorting exercises may include up to 100 items to sort and up to 12categories to group. One of the tasks may include categorizationcriteria such as asking participants questions “why do you group theseitems like this?.” Research module on research server 210 may combinecard sorting exercises and online questionnaire tools for detailedtaxonomy analysis. In an embodiment, the card sorting studies arecompatible with SPSS applications.

In an embodiment, the card sorting studies can be assigned randomly toparticipant 121. User experience (UX) researcher 181 and/or client 171may decide how many of those card sorting studies each participant isrequired to complete. For example, user experience researcher 181 maycreate a card sorting study within 12 tasks, group them in 4 groups of 3tasks and manage that each participant just has to complete one task ofeach group.

After presenting the thus created tasks to participants 121 throughvirtual moderator module (running on virtual moderator server 230) andcommunication link 135, the actions/responses of participants will becollected in a data collecting module running on a data collectingserver 260 via a communication link 135′. In an embodiment,communication link 135′ may be a distributed computer network and sharethe same physical connection as communication link 135. This is, forexample, the case where data collecting module 260 locates physicallyclose to virtual moderator module 230, or if they share the usabilitytesting system's processing hardware. In the following description,software modules running on associated hardware platforms will have thesame reference numerals as their associated hardware platform. Forexample, virtual moderator module will be assigned the same referencenumeral as the virtual moderator server 230, and likewise datacollecting module will have the same reference numeral as the datacollecting server 260.

Data collecting module 260 may include a sample quality control modulethat screens and validates the received responses, and eliminatesparticipants who provide incorrect responses, or do not belong to apredetermined profile, or do not qualify for the study. Data collectingmodule 260 may include a “binning” module that is configured to classifythe validated responses and stores them into corresponding categories ina behavioral database 270. Merely as an example, responses may includegathered web site interaction events such as clicks, keywords, URLs,scrolls, time on task, navigation to other web pages, and the like. Inone embodiment, virtual moderator server 230 has access to behavioraldatabase 270 and uses the content of the behavioral database tointeractively interface with participants 121. Based on data stored inthe behavioral database, virtual moderator server 230 may directparticipants to other pages of the target web site and further collecttheir interaction inputs in order to improve the quantity and quality ofthe collected data and also encourage participants' engagement. In oneembodiment, virtual moderator server may eliminate one or moreparticipants based on data collected in the behavioral database. This isthe case if the one or more participants provide inputs that fail tomeet a predetermined profile.

Usability testing system 150 further includes an analytics module 280that is configured to provide analytics and reporting to queries comingfrom client 171 or user experience (UX) researcher 181. In anembodiment, analytics module 280 is running on a dedicated analyticsserver that offloads data processing tasks from traditional servers.Analytics server 280 is purpose-built for analytics and reporting andcan run queries from client 171 and/or user experience researcher 181much faster (e.g., 100 times faster) than conventional server system,regardless of the number of clients making queries or the complexity ofqueries. The purpose-built analytics server 280 is designed for rapidquery processing and ad hoc analytics and can deliver higher performanceat lower cost, and, thus provides a competitive advantage in the fieldof usability testing and reporting and allows a company such as UserZoom(or Xperience Consulting, SL) to get a jump start on its competitors.

In an embodiment, research module 210, virtual moderator module 230,data collecting module 260, and analytics server 280 are operated inrespective dedicated servers to provide higher performance. Client(sponsor) 171 and/or user experience research 181 may receive usabilitytest reports by accessing analytics server 280 via respective links 175′and/or 185′. Analytics server 280 may communicate with behavioraldatabase via a two-way communication link 272.

In an embodiment, study content database 220 may include a hard diskstorage or a disk array that is accessed via iSCSI or Fibre Channel overa storage area network. In an embodiment, the study content is providedto analytics server 280 via a link 222 so that analytics server 280 canretrieve the study content such as task descriptions, question texts,related answer texts, products by category, and the like, and generatetogether with the content of the behavioral database 270 comprehensivereports to client 171 and/or user experience researcher 181.

Shown in FIG. 2 is a connection 232 between virtual moderator server 230and behavioral database 270. Behavioral database 270 can be a networkattached storage server or a storage area network disk array thatincludes a two-way communication via link 232 with virtual moderatorserver 230. Behavioral database 270 is operative to support virtualmoderator server 230 during the usability testing session. For example,some questions or tasks are interactively presented to the participantsbased on data collected. It would be advantageous to the user experienceresearcher to set up specific questions that enhance the usabilitytesting if participants behave a certain way. If a participant decidesto go to a certain web page during the study, the virtual moderatorserver 230 will pop up corresponding questions related to that page; andanswers related to that page will be received and screened by datacollecting server 260 and categorized in behavioral database server 270.In some embodiments, virtual moderator server 230 operates together withdata stored in the behavioral database to proceed the next steps.Virtual moderator server, for example, may need to know whether aparticipant has successfully completed a task, or based on the datagathered in behavioral database 270, present another tasks to theparticipant.

Referring still to FIG. 2, client 171 and user experience researcher 181may provide one or more sets of questions associated with a target website to research server 210 via respective communication link 175 and185. Research server 210 stores the provided sets of questions in astudy content database 220 that may include a mass storage device, ahard disk storage or a disk array being in communication with researchserver 210 through a two-way interconnection link 212. The study contentdatabase may interface with virtual moderator server 230 through acommunication link 234 and provides one or more sets of questions toparticipants via virtual moderator server 230.

FIG. 3A is a flow diagram of an exemplary process of interfacing withpotential candidates and prescreening participants for the usabilitytesting according to one embodiment of the present invention. Theprocess starts at step 310. Initially, potential candidates for theusability testing may be recruited by email, advertisement banners,pop-ups, text layers, overlays, and the like (step 312). The number ofcandidates who have accepted the invitation to the usability test willbe determined at step 314. If the number of candidates reaches apredetermined target number, then other candidates who have signed uplate may be prompted with a message thanking for their interest and thatthey may be considered for a future survey (shown as “quota full” instep 316). At step 318, the usability testing system further determineswhether the participants' browser comply with a target web site browser.For example, user experience researchers or the client may want to studyand measure a web site's usability with regard to a specific web browser(e.g., Microsoft Internet Explorer) and reject all other browsers. Or inother cases, only the usability data of a web site related to Opera orChrome will be collected, and Microsoft IE or FireFox will be rejectedat step 320. At step 322, participants will be prompted with a welcomemessage and instructions are presented to participants that, forexample, explain how the usability testing will be performed, the rulesto be followed, and the expected duration of the test, and the like. Atstep 324, one or more sets of screening questions may be presented tocollect profile information of the participants. Questions may relate toparticipants' experience with certain products, their awareness withcertain brand names, their gender, age, education level, income, onlinebuying habits, and the like. At step 326, the system further eliminatesparticipants based on the collected information data. For example, onlyparticipants who have used the products under study will be accepted orscreened out (step 328). At step 330, a quota for participants having atarget profile will be determined. For example, half of the participantsmust be female, and they must have online purchase experience or havepurchased products online in recent years. If the quota reaches apredetermined target number, a message shown as “quota full” in step 332is displayed to the participants. In some embodiments, the process endsat 333.

FIG. 3B is a flow diagram of an exemplary process for gatheringusability data of a target web site according to an embodiment of thepresent invention. The process starts at 333. At step 334, the targetweb site under test will be verified whether it includes a proprietarytracking code. In an embodiment, the tracking code is a UserZoom®JavaScript® code that pop-ups a series of tasks to the pre-screenedparticipants. If the web site under study includes a proprietarytracking code (this corresponds to the scenario shown in FIG. 1C), thenthe process proceeds to step 338. Otherwise, a virtual tracking codewill be inserted to participants' browser at step 336. This correspondsto the scenario described above in FIG. 1A.

The following process flow is best understood together with FIG. 2. Atstep 338, a task is described to participants. The task can be, forexample, to ask participants to locate a color printer below a givenprice. At step 340, the task may redirect participants to a specific website such as eBay®, HP®, or Amazon®. The progress of each participant inperforming the task is monitored by a virtual study moderator at step342. At step 344, responses associated with the task are collected andverified against the task quality control rules. The step 344 may beperformed by the data collecting module 260 described above and shown inFIG. 2. Data collecting module 260 ensures the quality of the receivedresponses before storing them in a behavioral database 270 (FIG. 2).Behavioral database 270 may include data that the client and/or userexperience researcher want to determine such as how many web pages aparticipant viewed before selecting a product, how long it took theparticipant to select the product and complete the purchase, how manymouse clicks and text entries were required to complete the purchase andthe like. A number of participants may be screened out (step 346) duringstep 344 for non complying with the task quality control rules and/orthe number of participants may be required to go over a series oftraining provided by the virtual moderator module 230. At step 348,virtual moderator module 230 determines whether or not participants havecompleted all tasks successfully. If all tasks are completedsuccessfully (e.g., participants were able to find a web page thatcontains the color printer under the given price), virtual moderatormodule 230 will prompt a success questionnaire to participants at step352. If not, then virtual moderator module 230 will prompt an abandon orerror questionnaire at 350 to participants who did not complete alltasks successfully to find out the causes that lead to the incompletion.Whether participants have completed all task successfully or not, theywill be prompted a final questionnaire at step 356. In some embodiments,the process ends at 357.

FIG. 3C is a flow diagram of an exemplary process for card sortingstudies according to one embodiment of the present invention. Theprocess starts at 357. At step 360, participants may be prompted withadditional tasks such as card sorting exercises. Card sorting is apowerful technique for assessing how participants or visitors of atarget web site group related concepts together based on the degree ofsimilarity or a number of shared characteristics. Card sorting exercisesmay be time consuming. In an embodiment, participants will not beprompted all tasks but only a random number of tasks for the cardsorting exercise. For example, a card sorting study is created within 12tasks that is grouped in 6 groups of 2 tasks. Each participant justneeds to complete one task of each group. It should be appreciated toone person of skill in the art that many variations, modifications, andalternatives are possible to randomize the card sorting exercise to savetime and cost. Once the card sorting exercises are completed,participants are prompted with a questionnaire for feedback at step 362.The feedback questionnaire may include one or more survey questions suchas a subjective rating of target web site attractiveness, how easy theproduct can be used, features that participants like or dislike, whetherparticipants would recommend the products to others, and the like. Atstep 364, the results of the card sorting exercises will be analyzedagainst a set of quality control rules, and the qualified results willbe stored in the behavioral database 270. In an embodiment, the analyzeof the result of the card sorting exercise is performed by a dedicatedanalytics server 280 that provides much higher performance thangeneral-purpose servers to provide higher satisfaction to clients. Ifparticipants complete all tasks successfully, then the process proceedsto step 368, where all participants will be thanked for their timeand/or any reward may be paid out. Else, if participants do not complyor cannot complete the tasks successfully, the process proceeds to step366 that eliminates the non-compliant participants.
